Further, when it is decided that a detailed description for the known function or configuration related to the present invention may obscure the gist, the detailed description will be omitted. Furthermore, the following terminologies are defined in consideration of the functions in the present invention and may be construed in different ways by the intention of users and operators. Therefore, the definitions thereof should be construed based on the contents throughout the specification. Also, well-known functions or constructions are not described in detail since they would obscure the invention with unnecessary detail.

FIG. 1 is a block diagram illustrating a configuration of a display apparatus, according to an exemplary embodiment.

Referring to FIG. 1, a display apparatus 100 is configured to include a display 110, an input unit 120, and a processor 130. The display apparatus 100 may be implemented as various types of electronic devices such as TV, an interactive whiteboard, an electronic table, a large format display (LFD), a smart phone, a tablet, a desk top PC, and a notebook.

The display 110 may display various objects such as all the moving picture images or still images which may be created using a plurality of images such as a movie, a drama, a recorded image, and a slow video, and displayed at a predetermined frame ratio, pictures, and documents. Furthermore, the display 110 may display a user interface screen which includes various kinds of menus. The user interface screen may include various kinds of menus, for example, volume up/down, channel up/down, environment setting menus, and the like, which control the display apparatus 100.

For this purpose, the display 110 may be implemented as a liquid crystal display (LCD), an organic light emitting display (OLED), a plasma display panel (PDP), or the like.

The input unit 120 may receive various user operations which control the display apparatus 100. In particular, the input unit 120 may receive the user operation which selects and carries out at least one menu which is included in the user interface screen displayed on the display 110.

Further, the input unit 120 according to the exemplary embodiment includes at least one of a single physical function key and a touch panel.

Further, the single physical function key refers to a hot key, a one key, and a single key.

Meanwhile, the processor 130 may separately recognize a short click and a long press based on an input time of a user operation which is input through the input unit 120. The short click and the long press will be described in detail with reference to FIGS. 2A and 2B.

FIGS. 2A and 2B are diagrams for describing the short click and the long press, according to the exemplary embodiment.

Referring to FIGS. 2A and 2B, when the user operation is not input, a voltage V is maintained at a predetermined constant value and sections 210 and 220, in which a voltage is reduced, are created as long as the user operation is input, according to an exemplary embodiment.

When the user operation is input, if the sections 210 and 220, in which the corresponding voltage is reduced, are within 1 second, the processor 130 recognizes the user operation as the short click, and if the sections 210 and 220, in which the voltage is reduced, exceed 1 second, the processor 130 recognizes the user operation as the long press.

FIGS. 2A and 2B are diagrams for separately describing the short click and the long press depending on whether the time taken to input the user operation exceeds 1 second or not, however, the time taken to input the user operation for distinguishing the short click and the long press is not limited to 1 second and therefore may be changed depending on the user setting.

The processor 130 may carry out different functions corresponding to each of the short click and the long press which are separately recognized depending on the input time of the user operation, which will be described below.

Furthermore, the processor 130 may constantly keep an execution speed of the functions corresponding to the selected menu within a preset critical time, in a time for which the input of the long press is continued, and may accelerate the execution speed of the corresponding function after the preset critical time.

That is, the processor 130 may make the execution speeds of the functions, which correspond to the selected menu within the preset critical time and after the preset critical time in the time for which the input of the long press is continued under the condition that the long press is input, different from each other. How to discriminate the section within the preset critical time and the section after the preset critical time in the time for which the input of the long press is continuously input will be described with reference to FIGS. 3A and 3B.

FIGS. 3A and 3B are diagrams for describing an example of the long press, according to the exemplary embodiment.

Referring to FIG. 3A, in the section 310, within the preset critical time in the time for which the input of the long press is continued, a control function may be executed every 1 second. Referring to FIG. 3B, in the section 320, after the preset critical time in the time for which the input of the long press is continued, the control function may be executed every 0.5 seconds, which are smaller than 1 second, according to an exemplary embodiment.

The processor 130 may execute the control function every 1 second in the section 310, within the preset critical time in the time for which the input of the long press is continued to keep the execution speed of the function corresponding to the selected menu constant, and may execute the control function every 0.5 seconds which is smaller than 1 second in the section 320, after the preset critical time to accelerate the execution speed of the functions corresponding to the selected menu.

For example, when the selected menu is the volume up menu, the processor 130 executes the control function every 1 second in the section 310, within the preset critical time in the time for which the input of the long press is continued to sequentially increase volume intensity, such as 1, 2, 3, 4, . . . , and executes the control function every 0.5 seconds, which is smaller than 1 second, in the section 320, after the preset critical time in the time for which the input of the long press is continued to more rapidly increase the volume intensity like 7, 10, 15, 22, . . . , according to an exemplary embodiment.

Specifically, the processor 130 may constantly keep a sampling section in which the input of the long press is recognized at a preset size within the preset critical time, and may change the sampling section in which the input of the long press is recognized to a size which is smaller than the preset size, after the preset critical time.

That is, the processor 130 sets the sampling section in which the input of the long press is recognized at the interval of 1 second within the preset critical time to execute the sampling so as to recognize that the long press is continuously input, thereby executing the control function every 1 second, according to an exemplary embodiment.

Furthermore, the processor 130 sets the sampling section in which the input of the long press is recognized at an interval of 0.5 seconds, which is smaller than 1 second, after the preset critical time to execute the sampling so as to recognize that the long press is continuously input, thereby executing the control function every 0.5 seconds, according to an exemplary embodiment.

Although FIGS. 3A and 3B describe that the control function is executed every 1 second in the section 310, within the preset critical time in the time for which the input of the long press is continued and the control function is executed every 0.5 seconds, which is smaller than 1 second, in the section 320, after the preset critical time, the interval in which the control function is executed is not limited to 1 second and 0.5 seconds and may be smaller or larger.

Furthermore, FIGS. 3A and 3B describe that the preset critical time is set to be 2 seconds. However, the preset critical time may be changed depending on the user settings. For example, as the user increases the preset critical time, the input of the long press needs to be relatively longer continuing to accelerate the execution speed of the functions corresponding to the selected menu.

Meanwhile, in the foregoing example, the processor 130 is a component which generally serves to control apparatuses and may be used as a central processing unit, a microprocessor, a controller, and the like and may control an overall operation of the apparatuses and may be implemented as a system-on-a-chip or system on chip (SOC, SoC).

The main CPU 133 accesses the storage unit 140 to execute booting using the O/S stored in the storage unit 140. Further, the main CPU 133 executes various operations using various programs, contents, data, and the like which are stored in the storage unit 170, according to an exemplary embodiment.

A set of commands for system booting, and the like may be stored in the ROM 132. When a turn on command is input, in-turn inputting the power, the main CPU 133 copies an O/S stored in the storage unit 140 to the RAM 131 according to the command stored in the ROM 132 and executes the O/S to boot the system. When the booting is completed, the main CPU 133 copies various application programs stored in the storage unit 140 to the RAM 131 and executes application programs copied to the RAM 131 to execute various operations, according to an exemplary embodiment.

The graphic processor 134 uses an operator (not illustrated) and a renderer (not illustrated) to create a screen including various objects such as an icon, an image, and a text. The operator (not illustrated) operates attribute values, such as coordinate values, forms, sizes, and colors which will be displayed by each object according to a layout of the screen, based on the received control command, according to an exemplary embodiment. The renderer (not illustrated) creates the screen of various layouts including an object based on the attribute values which are operated by the operator (not illustrated), according to an exemplary embodiment. The screen created by the renderer (not illustrated) may be displayed on the display 110, according to an exemplary embodiment.

The foregoing operation of the processor 130 may be executed by programs which are stored in the storage unit 140.

The storage unit 140 stores various data such as an operation system (O/S) software module for driving the display apparatus 100′, and various kinds of multimedia contents, according to an exemplary embodiment.

Specifically, the storage unit 140 includes various software modules which allow the processor 130 to separately recognize the short click and the long press based on the input time of the user operation, constantly maintain the execution speed of the function corresponding to the selected menu within the preset critical time in the time for which the input of the long press is continued, and accelerate the execution speed of the corresponding function after the preset critical time, according to an exemplary embodiment. This will be described in more detail below with reference to FIG. 5.

The sensor unit 150 may include various kinds of sensors, for example, a touch sensor for recognizing a touch, a motion sensor for sensing a motion of a user, and the like.

The audio processor 160 may process an audio signal to meet user setting about an output range of a speaker unit 110 and a sound quality.

FIG. 5 is a diagram illustrating the software module stored in the storage unit, according to an exemplary embodiment.

Referring to FIG. 5, the storage unit 140 may store programs such as a user operation discrimination module 141, a long press input sampling module 142, a short click execution module 143, a long press execution module 144, an OSD creation module 145, and the like.

The foregoing operation of the processor 130 may be executed by programs which are stored in the storage unit 140. The detailed operation of the processor 130, using the programs stored in the storage unit 140, will be described below in detail.

The user operation discrimination module 141 may execute a function of discriminating the short click and the long press depending on the input time of the user operation. For example, the user operation discrimination module 141 may perform a function of recognizing the case in which the input time of the user operation does not exceed 1 second as the short click and the case in which the input time of the user operation exceeds 1 second as the long press.

The long press input sampling module 142 may execute a function of constantly maintaining the sampling section in which the long press input is recognized at a preset size to execute the sampling within the preset time in the time for which the input of the long press is continued and changing the sampling section in which the input of the long press is recognized to a smaller size than the preset size to execute the sampling after the preset critical time.

The short click execution module 143 and the long press execution module 144 may execute functions of executing the control commands corresponding to the recognized short click and long press.

The on screen display (OSD) creation module 145 may execute a function of creating an OSD which is displayed on the display 110.

As such, the processor 130 may use various software modules stored in the storage unit 140 to separately recognizes the short click and the long press based on the input time of the user operation and adjust the execution speeds of the functions corresponding to the selected menus within the preset critical time and after the preset critical time in the time for which the input of the long press is continued to be different.

The processor 130 may create the on screen display (OSD) which guides the functions corresponding to each of the short click and the long press and display the created OSD on the display 110.

FIG. 6 is a diagram for describing an example of the OSD, according to an exemplary embodiment. Referring to FIG. 6, an OSD 610 displays that the function corresponding to the short click is a function of moving a selected GUI and the function corresponding to the long press is a function of selecting and executing a menu at which the selected GUI is positioned.

Furthermore, graphics displaying that shortly pressed item is the short click and long pressed item is the long press, displayed beside each of the short click and the long press. Using this, the user may easily recognize a method for inputting the short click and the long press. The user may also easily recognize what the functions corresponding to each of the input short click and long press are.

When the user operation is recognized as the short click, the processor 130 may move the selection GUI for selecting one of at least one menu included in the user interface screen and when the user operation is recognized as the long press, the processor 130 may select and execute the menu at which the selection GUI is positioned. This will be described in more detail below, with reference to FIG. 7.

Furthermore, the processor 130 may constantly keep a speed of increasing the channel number within the preset critical time in the time for which the input of the long press is continued and accelerate the speed of increasing the channel number after the preset critical time.

Further, the processor 130 changes a color of the selection GUI when the long press is recognized while moving the selection GUI to another menu by the short click to recognize the long press, thereby displaying that the function corresponding to the currently selected menu is executing, according to an exemplary embodiment.

Here, the selected GUI is implemented as a form enclosing the menu, but may be implemented by an arrow like a cursor and may also be implemented by changing a color of a menu.

Further, when the user input is not input for the preset time, the user interface screen 710 including the plurality of menus is faded out and thus disappears, according to an exemplary embodiment.

Specifically, the processor 130 may constantly maintain a channel change speed within the preset critical time and accelerate the channel change speed after the preset critical time when the menu at which the selection GUI is positioned is a channel change menu.

FIGS. 8 to 14 are diagrams for describing the channel change, according to an exemplary embodiment.

Referring to FIG. 12, the processor 130 recognizes that the long press is continuously input through the input unit 120 to perform the function of continuously increasing the channel number, thereby displaying the OSD 30 indicating that the current channel number is changed to number 7, according to an exemplary embodiment.

Referring to FIG. 13, the processor 130 may move the selection GUI from the channel up menu 712 included in the user interface screen 710 to a channel down menu 713 when the short click is input through the input unit 120, according to an exemplary embodiment. In this case, the processor 130 displays the OSD 30 indicating that the current channel number is number 7.

Referring to FIG. 14, the processor 130 executes the function corresponding to the channel down menu at which the selection GUI is positioned, that is, the function of lowering the channel number when the long press is input through the input unit 120, thereby displaying the OSD 20 indicating that the current channel number is changed to number 6, according to an exemplary embodiment.

Meanwhile, referring to FIGS. 8 to 14, when the long press is input, the processor 130 may sequentially increase channel numbers to numbers 5, 6, and 7 as illustrated in FIGS. 10, 11, and 12 within the preset critical time and, although not illustrated in the drawings, may increase the speed of surfing through numbers, such as 7, 10, and 15, without sequentially increasing the channel numbers as illustrated in FIGS. 10, 11, and 12 after the preset critical time. Furthermore, even in the case of lowering the channel number as illustrated in FIG. 14, when the long press is input, the channel number may be sequentially lowered within the preset critical time but the speed of lowering the channel number may be increased after the preset critical time.

The processor 130 may constantly maintain a volume change speed within the preset critical time and accelerate the volume change speed after the preset critical time when the menu at which the selected GUI is positioned is the volume change menu.
